Mjolnir is capable of granting its possessor the physical powers of Thor as well as control of the elements of weather
(wind, rain, snow, fog, thunder and lightning), project or absorb mystical energies, open dimensional portals, enable flight when
thrown without releasing the handle thong; always returning to the wielder when thrown and can not be lifted by any being deemed
unworthy by Odin. Additional enchantments have included a spell of concealment which mask the shape of the hammer as an ordinary walking
stick, and transforms the wielder into a mortal form. This enchantment has been removed and transferred to the hammer
Storm Breaker.

According to ancient Norse mythology, Mjolnir and other great weapons and ornaments were crafted by the dwarfs
Brokk and Eitri as a wager, instigated by the trickster
Loki, to see which was the better smith.

Loki was desperate to replace the hair of Thor's wife Sif, whom he cut off as a prank, but he had no money to pay the dwarfs. He wagered
his head that they could not create the wondrous things he described, including hair of gold for the lady Sif. After the items were wrought
the dwarfs took them to the gods for inspection and payment. When Odin declared that he had approved no such deal, the dwarfs demanded the
head of Loki, to which the gods did not object.

Ever the cleaver trickster, Loki agreed that he had wagered his head but not his neck, when one of the dwarfs attempted to cleave it from
his shoulders with a sword. Although their revenge was thwarted, the dwarfs sewed Loki's mouth shut and the gods had a time of peace and quite
from the god of evil.
